    Abstract: PURPOSE:To prepare the titled compound useful as a detergent and resistant to the lowering of the ester-content with time, with little hydrolysis of the product, easily, by mixing and neutralizing a liquid alpha-sulfo-fatty acid ester with powdery solid carbonate and/or bicarbonate. CONSTITUTION:A liquid alpha-sulfo-fatty acid ester is mixed and neutralized with (A) a powdery solid carbonate and/or (B) bicarbonate to obtain an alpha-sulfo-fatty acid ester salt. The amount of the component A and/or B is 1-150mol, preferably 4-60mol per 1mol of the alpha-sulfo-fatty acid ester. The component A or B is e.g. Na2CO3, K2CO3, NaHCO3, etc. A detergent composition having high hydrolysis resistance and cleaning property can be prepared by mixing the alpha-sulfo-fatty acid ester salt produced by the present process with other detergent components (e.g. spray-dried powder).
